Exception typeCondition

ExternalException

The Clipboard could not be cleared. This typically occurs when the Clipboard is being used by another process.

ThreadStateException

The current thread is not in single-threaded apartment (STA) mode. Add the STAThreadAttribute to your application's Main method.

Use this method to determine whether the Clipboard contains audio data before retrieving it with the GetAudioStream method.

NoteNote

The Clipboard class can only be used in threads set to single thread apartment (STA) mode. To use this class, ensure that your Main method is marked with the STAThreadAttribute attribute.

The following code example demonstrates the use of this member.

// Demonstrates SetAudio, ContainsAudio, and GetAudioStream.
public System.IO.Stream SwapClipboardAudio(
    System.IO.Stream replacementAudioStream)
{
    System.IO.Stream returnAudioStream = null;
    if (Clipboard.ContainsAudio())
    {
        returnAudioStream = Clipboard.GetAudioStream();
        Clipboard.SetAudio(replacementAudioStream);
    }
    return returnAudioStream;
}
